Kurwanya UV bivuga igishushanyo mbonera cyangwa ibicuruzwa kugirango bihangane kwangirika cyangwa kugabanuka bitewe nimirasire yizuba ya ultraviolet (UV).Ibikoresho birwanya UV bikoreshwa cyane mubicuruzwa byo hanze nk'imyenda, plastiki hamwe na kote kugirango bifashe kuramba no gukomeza kugaragara kubicuruzwa.
Nibyo, ibiciro bimwe byashizweho kugirango bibe birwanya UV.Iyi tarps ikozwe mubintu bivuwe bishobora kwihanganira kumara igihe kinini kumurasire yizuba bitangirika cyangwa gutakaza ibara.Ariko rero, ni ngombwa kumenya ko ibiciro byose bidashobora kwihanganira UV kandi bimwe bishobora kwangirika mugihe iyo bihuye nizuba.Mugihe uhisemo tarp, nibyiza kugenzura ikirango cyangwa ibicuruzwa byihariye kugirango umenye neza ko irwanya UV niba ibi ari ngombwa kubyo ukoresha.
Urwego rwa UV irwanya ibiciro biterwa nibikoresho byabo hamwe na UV stabilisateur zikoreshwa mubikorwa byazo.Muri rusange, ibiciro birwanya UV bipimwa nijanisha bahagarika cyangwa bakuramo imirasire ya UV.Sisitemu ikunze gukoreshwa ni Ultraviolet Protection Factor (UPF), igereranya imyenda ukurikije ubushobozi bwabo bwo guhagarika imirasire ya UV.Urwego rwo hejuru rwa UPF, nibyiza kurinda UV.Kurugero, UPF 50-igipimo cya tarp ihagarika hafi 98 ku ijana yimirasire ya UV.Ariko, ni ngombwa kumenya ko urwego nyarwo rwo kurwanya UV rushobora nanone guterwa nimpamvu nko izuba, imiterere yikirere hamwe nubuziranenge bwa tarp.
